A sample has a Subscript 6 Superscript 14 Baseline Upper C activity of 0.0060 Bq per gram of carbon. (a) Find the age of the sample, assuming that the activity per gram of carbon in a living organism has been constant at a value of 0.23 Bq. (b) Evidence suggests that the value of 0.23 Bq might have been as much as 23% larger. Repeat part (a), taking into account this 23% increase.

Background (Part 1): We are continuously exposed to ionizing radiation from natural and artificial sources. All of us are exposed to radiation every day, from natural sources such as minerals in the ground and cosmic radiation to man-made sources such as medical x-rays. According to the National Council on Radiation Protection and Measurements (NCRP), the average annual radiation dose per person in the U.S. is 620 millirem. In this activity, you will use the interactive online dose calculator to estimate...
